Disability accompanying occupational low back pain (LBP) can include a wide range of incapacitating symptoms which, for the practitioner, can be time-consuming and difficult to identify systematically. A questionnaire designed for case-finding and assessment could assist in both the early recognition of disability and in planning management. A suitable questionnaire for clinical use could not be...
The relationship of Workers' Compensation and litigation to low back pain (LBP) outcome is not established in the literature. Our study investigated the characteristics of disabled persons applying for Worker's Compensation or employing a lawyer, the factors predicting receipt of compensation, and the effects of compensation and litigation on employment outcome. One hundred sixty-nine unemployed...
Two studies are presented that investigated fear of movement/(re)injury in chronic musculoskeletal pain and its relation to behavioral performance. The 1st study examines the relation among fear of movement/(re)injury (as measured with the Dutch version of the Tampa Scale for Kinesiophobia (TSK-DV)) (Kori et al. 1990), biographical variables (age, pain duration, gender, use of supportive equipment,...
The family climate in 36 families, comprising 154 individuals, was investigated. The objective of this study was to compare families where the mother suffered from chronic headache to families with pain-free mothers and to those where the mother suffered from chronic low back pain. The Family Environment Scale (FES) was used to evaluate the family climate in these 3 groups as perceived by the members...

We asked 78 chronic low back pain patients to report on their usual pain intensity, and on the lifestyle changes caused by their pain, on a horizontally-oriented visual analogue scale (VAS). Also, the usual and the current pain intensities were examined on a vertical VAS. Statistical analysis showed normal distribution of data in the measurement of usual pain on the horizontal VAS, but no homogeneous...
Temporary nerve blocks using local anesthetic are employed extensively in the evaluation of pain problems, particularly lumbosacral spine disease. Their specificity and sensitivity in localizing anatomic sources of pain have never been studied formally, however, and so their diagnostic and prognostic value is questionable. There have been anecdotal reports of relief of pain by temporary blocks directed...
This study compares the responsiveness of three instruments of functional status: two disease-specific questionnaires (Oswestry and Roland Disability Questionnaires), and a patient-specific method (severity of the main complaint). We compared changes over time of functional status instruments with pain rated on a visual analog scale. Two strategies for evaluating the responsiveness in terms of sensitivity...
Researchers have typically used factor-analytic composite measures of coping, instead of individual scales, to predict rehabilitation outcome. There are, however, both advantages and disadvantages to using individual or composite scores. This study extended the findings of Jensen et al. (1992), by prospectively comparing the individual and composite scores of the Coping Strategies Questionnaire (CSQ)...
Previous retrospective studies have suggested that patient demographics may influence analgesic administration. These studies have not taken physicians' impression of patient pain into account. This prospective study investigates the influence of (i) physician impression of the degree of pain and (ii) patient demographics on the use of analgesic. A convenience sample of adults with non-traumatic lower...
The construct of coping is explored in this paper utilising repertory grid technique with a small group of non-patients with chronic pain. Nineteen volunteers with low back pain completed a repertory grid with eight given elements signifying various self and illness-related roles. Two constructs were given and the remainder elicited using the triad method. The 19 participants rated themselves as being...
Efforts to examine the process and risk of developing chronic back pain have relied generally upon retrospective study of individuals with already established pain. In an alternative approach to understanding the clinical course and evolution of low back disorders, a cohort of 76 men experiencing their first episode of back pain was assessed prospectively at 2, 6 and 12 months following pain onset...
The aim of this study was to assess the long-term effect of a supervised fitness programme on patients with chronic low back pain. The design of the study was a single blind randomised controlled trial with follow-up, by postal questionnaire, 2 years after intervention. The Oswestry Low Back Pain Disability Index was used as the outcome measure to assess daily activity affected by back pain. Eighty-one...
The inability to predict outcome in patients with low back/neck pain leads to inappropriate or unnecessary treatment. The aims of the study were to identify prognostic factors for disability at 1-year follow-up in patients with back pain visiting primary care, and to compare the effect of these in two treatment strategies - chiropractic and physiotherapy. Data were taken from a randomised trial on...
Low back pain symptoms are extremely common, affecting as many as 80% of the population at some time in their lives. However, the majority of the medical costs arise from the minority of patients whose symptoms become chronic. The authors propose a model in which chronicity is determined not only by factors related to the episode of low back pain, but also factors prior to the onset of symptoms (pre-morbid...
This experiment was set up to test the hypothesis that confrontation with feared movements would lead to symptom-specific muscular reactivity in chronic low back pain patients who report high fear of movement/(re)injury. Thirty-one chronic low back pain patients were asked to watch a neutral nature documentary, followed by a fear-eliciting video-presentation, while surface electromyography (EMG) recordings...
The aim of this study was to explore whether accelerations of the lower back during walking are temporarily attenuated by experimentally-induced low back pain, as compared with normal walking. Transient low back pain was induced by injection of 1 ml 6% hypertonic saline in the longissimus dorsi muscle in 20 healthy subjects. Acceleration was measured during walking at self-selected speeds before and...
The purpose of this Dutch prospective population-based study was to identify prognostic factors for return-to-work of employees with 3-4 months sick leave due to low back pain (LBP). A cohort of 328 employees was formed and baseline data were collected. One year after the first day of the sick leave, 91% of the original cohort participated in a second interview (n=298). During the baseline measurement,...
While psychosocial factors are known to influence treatment outcomes in low back pain patients, relatively little is known about how they may influence work injury management of low back pain. This study examined medical and psychosocial factors associated with work injury management decisions relative to patients with occupational low back pain. A retrospective review of 132 patients who had settled...
A number of ergonomic, workplace and individual psychosocial factors and health behaviors have been associated with the onset, exacerbation and/or maintenance of low back pain (LBP). The functional impact of these factors may be influenced by how a worker approaches problems in general. The present study was conducted to determine whether problem-solving orientation was associated with physical and...
